Does Crouse Mobile Home Park & Sales, LLC have drinking water violations?
Of the 12 most recent violations in EPA's records, 2 are health-based, and the most recent began in July 2025. The violations listed here began between December 2012 and July 2025.

The contaminant or rule involved most often is Total coliform bacteria (TCR) (3 of them). EPA lists 8 as resolved, 3 as unaddressed and 1 as archived. Resolved means at least one resolving action is on record: the system returned to compliance, the rule no longer applies, or no further action was needed.

Archived means the violation was not marked resolved but is more than five years past the end of the noncompliance period, so it no longer counts toward current compliance status.
